Subject: Re: Countries that ban the use of crypto?



[China bans cryptography]


I'm not going to out anyone on this, but even a quick search of Skype finds 
quite a few individuals who make use of cryptography in China. So I strongly 
suspect that there is a great deal of lenience on that front. In fact, I 
have it on dependable authority that there are a number of places in China 
where the only IM system that functions is Skype.


I have no doubt that China does place controls on it, and it has been 
published a few places that their telecom industry has a particular distaste 
for Skype, but it appears that there is more to it.

impossible for your average Joe to actually be issued such a license.

You also have to remember that the severity of Russian law is compensated for
by its non-mandatoryness.  Those who care enough about complying (banks and so
on) shouldn't have much trouble getting the necessary license, everyone else
just goes ahead and uses crypto and no-one cares.

I've had a similar debate with banking users who only wanted integrity
protection and didn't care about confidentiality (or at least they didn't want
to invest the CPU time to provide confidentiality, since for their application
it wasn't warranted).

One of the best places on the net for this sort of information is the
'Crypto Law Survey' at http://rechten.uvt.nl/koops/cryptolaw/

They have maps showing import/export/domestic controls here:

Well, I suppose you could always check Bert-Jaap Koops' crypto law
survery (http://rechten.uvt.nl/koops/cryptolaw/).

However, there are only two countries, to the best of my knowledge,
that outright ban cryptography: Russia and China. And even that's only
a de-facto ban since both only require individuals to obtain a license
to use cryptography in any way, shape or form. From what I have heard,
it's nearly impossible for your average Joe to actually be issued such
a license. (Your average Joe in those countries is most likely more
concerned with putting food on the table anyhow but that's besides the
point.)

Israel has a license requirement as well. But since personal use is
exempt and the law allows for general licensing of software products,
it's pretty much a non-issue these days.
